PATENT OFFIC IMPROVEMENT IN CORN PLQWS ANDPLANTERS- Specificationforming part of Letters Patent No. l07,709,-dated September 27, 1870.

To all whom it may concern.-

Be it known that I, HENRY CLAY OSBORN, of the county of Clarke and Stateof Ohio, have invented certain new and usefulImprovements in Corn Flowsand Planters, of which the following is a specification.

My invention relates to certain improvements in the construction of thetongue, axle,

and attachments connected to the same in a two-wheeled corn plow andplanter, having a separate frame for the latter with the droppers andplanting-plows attached thereto, the whole of which can be easilyremoved and plows attached to the axle, which is constructed with alarge bow in the center to allow the machine to pass over the corn. Therear end of the tongue is attached to a cross-bar extending across thespace made by the bow in the axle, connecting the latter in line andbolted to the straight or outer. parts of the same when the machine isused as aplanter. The forward part of the tongue passes through aguidewayon the front of the machine, which has a series of holes and aholtpassing through the tongue at this point for adjusting the height ofthe same. When the planting-frame is placed upon the axle the bow partlies nearly parallel upon the tongue, a pair of metal hounds connectingthe tongue and axle together. Therearendsof the hounds turn inward,andare inserted into holes in the sides of the axle-bow, so that whenthe frame, with the planting attachments, is taken ofi and the bowthrown up perpendicularly the ends ofthe hounds act as journals, onwhichthe bow partially. revolves. On converting the machine from a.planter, t0.a' plow the bolts are taken out of the ends of the cross-barattach' ing it to the axle, the bow thrown up (backward)perpendicularly, the tongue raised up and attached to the top of the howby a bolt. The hounds now act as braces to strengthen and support thetongue. The cross-bar, being permanently attached'to the rear of thetongue,

is raised up with it. Rods depend from this cross-bar, upon which theplows are swung up for transportation from one field to another. Theplows areattached to the axle by anjad- 'justable plate-clevis, a lug ofwhich extends forward of the axle for attaching the draftrods. These areheld up by rods which depend from hooks on the ends of the double-t ree,havingaloop or eyein theirlower ends, through vation of my machine as acultivator.

1 and 2.

The object of suspending draft-rods din the manner shown is torelievethe horses necks from weight of tongue'A and at the same time give theline of draft directly-from the plows.

It will be seen by reference to the drawings that when the how B isthrown down forward from position shown in Figs. 1 and 2 to that seeninFig. 5 the cross-bar c comes,directly upon the back of the axleopposite the bow, the same bolts used in the clevises attaching, thecross-bar to the axle at the inner'holes. '(Seen in dotted lines on theaxle, Fig. 2 Y

G is the planterframe; E, guideway for tongue, with holes 0 and bolt 0for adjusting height of tongue. Pin'sp p (seen inserted in the axle onthe inside of frame G) prevent any lateral motion of the frame, whichsimply sets on the axle, and is only held'in position by these pins andbolt 0, securing the tongue in the guideway E.

In changing my machine from a planter to a plow, bolt o is taken out,the frame and its appendages raised up, and the tongue withdrawn bybacking the truck. The bolts securing cross-bar 0 to the axle are takenout, how- B of the axle thrown up, bringing tongue A with it, which isthen fastened by bolt a to the top of the bow, as shown in Figs. 1 and2. The

weight of theframc and accessories used inplanting are thus entirelydispensed with, and the machine rendered light and easily operated as acultivator-plow.
